For once, this isn't someone being clueless or lazy. The download link on that page is not working. Until the maintainer fixes it, people will have to get the mod elsewhere.
I happen to have the mod from that version, and from what I understand, all you really need is this attached file, which you can unzip in the Data folder of the unmodded version. (I'm actually not sure why the maintainer distributes the mod as a whole game.) It will probably work with 0.63 too since I don't remember that version adding any new items, but I'm not sure.
You must be registered to see the links
, however, could be found from the front page of the wiki.
